To all whom, it may concern.-

Be it :known that I, MORITZ LINDNER,13.

citizen of Germany, residing at Meuselwitz,

in the Empire of Germany, have invented a new and useful Improvement in Lubricators, of which the following is a specification.

This invention relates to lubricators for thick lubricants; and it consists inthe elements of improvementhereinafter more fully .pointed out In, the accompanying drawings, Figure I represents a bearing with a lubricator embodying my invention, partly in section. Fig.

II is a topview of the same. Fig. III is a 'cross section of a bearing, showing a lubricator made in a separate piece. Fig. IV is a vertical section, and Fig. Visa cross-section, of a lubricator arranged parallel to the turning shaft, showing the luhricator removable. Fig. VI is a vertical seetion of I a lubrieator fastened to the cap. Fig. VII is a cross-section, and Fig. VIII awplan, of the same. Fig. IX is a vertical section of the lubricating device arranged for the hubof awheel. Fig. X

is a cross-section, and Fig. XI an end view,-

of the same. Fig. XII is asectional side view of a modification, showing the cover surrounded by a ring. Fig. XIII is a top view,

- partly in section, of the same.

bricator and the central hub, a. Y

When the lubricator is first filled with a thick lubricant, the cover B is placed upon holes 6.

This chamber is provided with a centhe chamber A, so that the wing (2 comes close to the partition I) at the side opposite where the hole or passage 6 is made: the cover B this wing 01 will act as a piston in the annular space and force the thick lubricant gradually into the hole or passage 0.

In Figs. IX,-X, and XI the hub of the wheel is made with three or more annular cavities. A, from each of which holes or passages e communicate with the axle or shaft.

The cover B is provided witha corresponding number of wings, (3, fitting tight into these annular recesses, and which force, when the cover is turned, the thick lubricant into these Bolts a, passing through circular slots in the cover, .fiX this cov er in any position.

In Figs. XII and XIII the cover B is provided with an external ring, B, surrounding the hub of the wheel, and in which the bolt a is arranged for fixing the cover in any position.

The wing d is made tight against the sides. and bot-tom of the annular ring or chamber of the lubricator by suitable india rubber or leather packing. v

I am aware of Patent No. 95.370, granted to T. Moody,September28,1869,and ofPatent N 0. 287,963, granted to H. Reisert, November 6, 1883, and I do not claim the constructions therein described; but

I do claim- The combination of chamber A, having hub a, aperture 6, and partition 6, extending from hub to the wall of the chamber, with cover B, adapted to turn on chamber A and provided with wing 01, substantially as specified.

In test mony whereof I have signed my name to this specification in the presence of two subscribing witnesses;

MORITZ LINDNER.
